Letter from John R Casley Smith, Villejuif (Seine) to Howard Walter Florey Agrees that his "knife-carry" paper is rather involved - discusses reasons for elaborate nature of the paper, which he does not think can be shortened - plans to write about permeability of normal and abnormal ear lymphatics in a single paper - would be too unwieldy to include details of the "knife-carry" in this - would like to publish "knife-carry" paper as separate note on 'Journal of Ultrastructure Research'. 22 April 1962
